Currently, the following programs are available:
VJ 16 bit - the base application
VJVIDCAP - capture a video and select the frame for VJ
VT - trick timer based on the video
I will add more or if you want, make separate threads for each. Probably that would be good. Also we probably could use a thread for setup/installation based on some fine work by Dave Clark.

Just trying out the board. If this gets
posted, then it works. Good idea.

OK, now I have a few minutes, I wanted to put down the current development plan.
The current vj software is available at:
http://www.utoronto.ca/ski/water/software/vj/index.html
maintained by Terry Jones.
The current vj is a 16 bit program (vj01A4) and development is now discontinued which means no new features on this version. My current task is to upgrade this program to a 32 bit version which requires replacing several controls and other nasty internal stuff. However, once the development is complete the system will be ready to go for additional features.
The next program is vjvidcap (01n). This is a 32 bit program and works by itself or interoperates with vj. After the vj program is upgraded to 32 bit, I plan to integrate the two programs into one. I will probably still maintain the original 32 bit vj program as well for older hardware.
The Video Trick program (01v) is a 32 bit program and is currently working fine and available for enhancements. The one enhancement I have scheduled is for a 15 sec run to be used for barefoot.
Sign Driver - I have a small application called vjsign that outputs the results from vj on a serial port so that it can drive a message board.
New Stuff
I have several Boat Test programs that perform tracking for test purposes and also can be used for slalom record validation. I intend to make a specific record validation program (per Gene Davis and AWSA). There are some technology issues regarding overlay. Only a very few capture cards do Overlay and I have to examine the implications of doing generic overlay versus the specific overlay of the SE100 class card only.
OK, that is my 2 cents worth for the moment.

VJ and VIDCAP and PAL
This will only concern Pal users.
I would be keen to discuss issues specific to VIDCAP in the PAL environment. I am using a Pinnacle DC10+ capture card. If this is of interest to anyone, I can post the problems and workarounds that I have discovered with the patient help from the Master (Bob Corson).
If you are running successfully with this setup, I would be keen to here from you, as you know something that I don't!!
Cheers from New Zealand

VJ PAL
I have sucessfully been able to operate VJ using ATI 128 Wonder card, Pinnacle Studio PCTV and Hauppauge WinTv (reasonable. Unable to get Pinnacle DC10+ operating. It appears to be necessary to use a fast computer minimumm 333Mhtz and fast ATA Ultra ATA 66/100 hard drive. I am most interested in discussing with you the problems of PAL and its need for higher speed etc
Dennis if you can send me your E-Mail address we can get together on this. I have also been helped by Bob and Dave but I am not sure I know something that you do not. My E-Mail:-

Upgrade Plans
Well, as usual, everything is changing a bit. My initial plans for this season were to upgrade vj to a 32 bit program using ocx controls instead of the current vbx control which is only 16 bits. However, that may change. I have put out an initial version of a slalom path tracking program using the 32 bit controls. The controls I am using are ezAVI and ezVidCap which are freeware written by Ray Mercer which are VB replacements for the C++ controls supplied by MicroSoft (which are stand alone and must be used in a C++ environment). These controls are not directly WDM compatible. So I am looking at commercial controls from PegasusTools and LEAD Controls as a substitute.
If I am going to replace the current controls, it seems like a wasted effort to upgrade the program twice, once to the ez controls and then immediately to the commercial controls.
So, not to worry, everything works as is, this is mostly concerning future use. However, I did want to let you know what was going on.

hai bob,
i'm irwan from indonesia. On October 25th-30th, 2002, we are going to have a water ski national tournament. Since the tournament coming soon, we would like to ask you whether you can send us a software of video jump?
Thank you for your cooperation and looking forward for your soonest reply.
Regards,
irwan

I tried to send the software, but your mail system rejected the files as too large. I sent you the links for downloading also available on another post. Let's continue by direct email.

Bob,
I have just returned from the 2003 US Nationals in Texas. I oversaw the 3 jump measurement computers for several days. Overall I trained several people who had not used the the clip capture version. I am happy to say that it was well recieved and the general concenus was that this is an improvement. The only negative was platform stability issues which I was never able to discern a pattern to help fix the problem. A couple of operational suggestions that came from the experiance are: Reduce the number of button steps in the process; i.e. auto switch to the measure screen when the frame is selected, auto switch to the capture screen after unfreezing the measured frame. These are just a couple of comments that go hand in hand with a question I have on development progess of the next version of your program. These suggestions will be moot if you have a single program to replace the current two program suite. How has the battle been going on new programing tools to move the development on?

Boettcher System & Corson System
This may be of interest to a few people. At the
recent Panam Games in the Dominican Republic, the
tournament ran both systems. This was far from
an ideal site for shore setup, as there was a creek
that prevented any equipment from being installed
short of about the 50m distance. For the Corson
system, a camera viewpoint high in a palm tree was
able to produce adequate results for the Womens Jump.
The Boettcher system was a bit 'scissored' and had
some accuracy challenges on the shorter jumps.
For the Mens jumping, both systems were located
in a good position to produce accurate results.
Typical differences were of the order of 0.1 meter,
with no strange results. Usually, the Corson
system read slightly lower, but that may have been
because we were able to freeze the actual contact
frame in full detail. Both setups were not any
kind of permanent situation, and small amounts
in marking the buoys could have easily made the
difference.
The Boettcher system was set up primarily by
Robert Howerton (US), with Felix Loreo (Chile)
assisting. I supervised the Corson system setup,
with help from Larry Downes (US), and others.
Bob Corson and Jeffry Armstrong were present at
the event, which went well considering that it
was on a river site in a jungle in a country
that has only recently started running waterski
events.
The conclusion is that both systems will produce
good results that agree, when the systems are
well set up and monitored. EB

i am considering using a newer version of vidjmp than b97final (the one delivered in the complete package). but wat i do not want is to start using a 'test or beta' version as mentioned on the webpage.
who can tell me what version of vidjmp is a good mixture of stability/reliability and functionality/user convenience?
greetings,
pieter laurens baljon, netherlands
